I have a need to change up some tag configurations. As an example, we have a tag that contains several variations of “$OS - $SomeApp”, which makes it a right nuisance to apply rules for the OS (need a duplicate rule for each application tag, ugh). I want to split this to OS and Application tags. I can obviously do some search by tag and bulk edit in WATO, though this would set tags on hosts where they might otherwise be set by folders. I then also need to search through the ruleset and make a lot of manual adjustments.
I’m contemplating whether it might be more worth my while to do it by editing the config files rather than going through the web interface (which I have done some of before, I’m not uncomfortable with the concept).
I’m sure I’ll figure it out one way or another. This is more of an open question/discussion starter. Does anyone have any particular tips for approaching this? Interesting stories of having done this yourself with mistakes the rest of us could learn from?
